             abstract = "The objective of this work is to evaluate the accuracy of the 
                         positioning calculation and the guidance of Remotely Piloted 
                         Aircraft (RPA) using concepts of photogrammetry from images 
                         generated by onboard cameras, aiming at autonomous air navigation. 
                         The technique of image navigation uses orthomosaic and Digital 
                         Surface Models (DSM) as a reference and images obtained by the 
                         onboard camera during flight. When corresponding points are found 
                         between these images and the orthomosaic it is possible to 
                         calculate the position and attitudes of the perspective center of 
                         the camera. With the applied methodology it was possible to verify 
                         average errors in the order of 0.5 meters in the positioning and 
                         0.5º in the angle of attitudes of the camera. So the navigation 
                         through the image can reach values equal to or higher than the 
                         GNSS receivers without differential correction. Therefore, 
                         navigating through the image is a good alternative to enable 
                         autonomous navigation.",
